animated 3d Cube?

Hello there, do anyone know if its posible to make an animated 3d cube ?, i mean animating one face of the cube, i want to make a tv, so it must show some images,thanks.

And other thing, how can i make a sprite to look in the same perspective as a cube?, simulating all the movement like if it was a flat cube with 1px of width?

The solution to both is to use a sprite with a distort map. With a distort map you can position the corners of the sprite in 3d space with the help of some 3d math. It's not very trivial though.
